CAPSULE-FILLER.

Specification of Letters Patent.

Patented June 29, 1915.

Application filed March 14, 1914. Serial No. 824,762.

To all whom it may concern Be it known that we, STUART BROADWELL andCLARnNoE HOLLAWAY, citizens of the United States, residing atSpringfield, in the county of Sangamon and State of Illinois, haveinvented new and useful Improvements in Capsule-Fillers, of which thefollowing is a specification.

Our invention relates to improvements in capsule fillers.

The primary object of our invention is to provide a simple appliance foruse in the filling of capsules, in which means will be provided for thespeedy and accurate measuring of the powder, or like ingredient, withoutthe use of cumbersome devices, and which will be sanitary and efficient,and yet inexpensive of manufacture.

To accom lish the foregoing objects and to secure other and furtheradvantages in the matter of construction, arrangement, and use, ourinvention involves certain new and useful details of design andconstruction as will be hereinafter fully described and then pointed outspecifically in the appended claims.

In the accompanying drawings, forming part of this specification, Figure1 is a perspective view of a capsule filler embodying our invention.Fig. 2 is a longitudinal vertical sectional view through our capsulefiller. Fig. 3 is a sectional view of our capsule filler, taken on line22 of Fig. 2.

In all figures, like characters of reference wherever they occurindicate corresponding parts.

The capsule filler of our invention may be cast of brass, or the like,or may be formed of glass, or other non-porous material, and ispreferably formed in a single piece. Numeral 1 designates the trayportion, supported for convenience by supporting flanges designated as2. Tray 1 is provided with a series of parallel lateral grooves 3,semi-circular in cross-section, and of equal depth and width, whichgrooves are of constantly decreasing depth adjacent each end, the bottomof the grooves rounding upward at each edge of the tray. (See Fig. 3.)Grooves 3 are formed of apredetermined ca pacity, that is, of a size tohold an approximately lmown quantity of powder when filled to the levelof the top of the tray. The capsule body may then be inserted, open endinward, at one end of the groove, and the capsule top, also open endinward, at the opposite end of the groove, and the two brought togetheralong the groove. It will be readily seen that the powder lying in thegroove will be taken up by the two capsule elements as they are broughttogether, and that a negligible portion of the powder will escape.

- We prefer to provide our device with a longitudinally extending flange5 on one side of the tray, upon which the consecutive numbers of thegrooves may be indicated. Thus the operator may readily see the exactnumber of capsules that have been filled, or divide the powder evenlyamong a given number of capsules with absolute accuracy, it being onlynecessary to use a straight-edged tool of any kind to smooth off thepowder in the grooves which are filled above the level of the tray.

From the foregoing description, it will be readily seen that ourinvention provides an inexpensive and simple device wherein capsules maybe filled readily and speedily, and in which accurate means are providedfor proportioning the material for the capsules and measuring it withconsiderable accuracy.

While we have described and shown the preferred embodiment of ourinvention, we do not wish to be limited strictly thereto, except forsuch limitations as the claims may import.

Having thus described our invention, what we claim is 1. A tray for usein filling capsules, comprising grooves semi-circular in cross-section,and said grooves being formed with constantly decreasing depth at eachcan tremity.

2. A tray for use in filling capsules, comprising a plurality of groovessemi-circular in cross-section adapted to receive material to beinserted in capsules, said grooves being formed with constantlydecreasing depth at each extremity and each of said grooves providing aslide-way whereby the open ends of a capsule may be brought togetheralong said groove and the material contained in said groove inserted inthe capgrooves being formed with constantly desule. creasing depth ateach extremity.

3. A tray for use in filling capsules, com- STUART BBOADWELL. prising aplurality of identical parallel CLARENCE HOLLAWAY. 5 groovessemi-circularin cross-sectionand of Witnesses:
